MQPI-18
®
28 Volt Input, 7 Amp MIL COTS EMI Filter for V•I Chips
Description
Typical Applications
The MQPI-18 attenuates conducted common-mode
(CM) and differential mode (DM) noise for 28 V input
MIL PRMs to comply with MIL-461E EMI requirements
for conducted noise measurements. The filter operates
within the full input operating range of a 28 V MIL
PRM and supports 7 A loads up to 60°C without
derating.
